Application filed April 4, 1911. SeriaLNo. 618,93L1 i To all whom it may concema'.

Be it known. thatI, AMAUDUS1SIGFRID STENBORG, of the city; of Guelph, in the county of l/Vellington, in the Province of Ontario, Canada, have invented certainnew and useful Improvements in Bearings :for

Cream-Separators, of which the following is the specification.

My invention relates to improvements in bearings for cream separators and the object of the invention is to devise means whereby the vertical worm; spindle and centrifuge supported thereby are rendered self balancing thereby obviating itheinecessity of balancing the centrifuge when set in the ma-. chine and it consists essentially of a sleeve provided at one end with a verticalbearing through which the worm spindle extends and at the lower end with a ball step bearon which the lower end ofthe worm spindle rests, a 1 vertical slot extending. through the sleeve at the inner side through:

which the main worm gear of the separator extends so as to mesh with the wormbf the worm spindle, aspherical enlargementforming part of the. sleeve and asocket bearing into which the spherical enlargement is fitted and held, the center of such enlargement and socket being located horizontally opposite the center of the worm: gear of the separator and. yieldably resilient means whereby the upper. end of the sleeve is supported in the frame of the support as here inafter more particularlydescribed by the following specification.

Figure 1, is a sideelevation mostly in: section of my device. Fi.g.; 2,;isa plan section on line w-y Fig. :1. Fig. 3, is a detail; elevation partially in SGCtlOIllOf the socket bearing and sleeve mounted therein looking from the front. Fig l, is a detail of the Worm spindle supporting sleeve. Fig. 5, is a perspective detail; of the: yieldable resilient means for supporting. the upper end of the sleeve. Figs. 6 and 7 are perspective detail A having an enlargement A at its upper:

end.

A is also ancxtension of the main frame forming the lower: bearing socket sup port A.

A and A are socket members fitting withinzthe socket support A. The members A 9 andA are slotted at A A Bis the bearing sleeve for supporting the vertical lworm spindle Cof the separator. Om the. worm spindle G is supported the.

usual centrifuge C surrounded by the bowl 0 secured to the main frame of the S6133: ratorr The sleeve B is provided withia vertical slot B", and a spherical enlargement B through wvhich the slot B also extends. The enlargement B is desi ned to fit within the socket members A and A3 horizontally op posite the center of the worm gear A B1; is an enlargement of the upperend of 1 the sleeveB inwhich fits a suitable bushing: B throughiwhichrextends the upper end of 1 the wormspindle C.

D is a .ballbearing held in a suitable cup D and forming a stepbearin for the lower end C? of the worm spindle A 5. is a set screw extending through the socket support A, through the socket mem-. bers A and A into a recess 0" formed in the spherical enlargement B By this 1 means thesleeve is prevented from turning 1 in a horizontal plane within the sockets F. is a coil spring, the upper portioni F? .90 1 F is will be seen from referring to Fig. 1 the upper portionaF fits 1 the internal periphery of the recess .A' and the lower portion F fits around the outer periphery of the enlargement B of the 1 of such springbeinmlar er in diameterthan the lower portion sleeve B, with the lower end of the spring resting upon the shoulder formed by the bottom of the enlarged portion A. By this means the upper end of the sleeve is ayieldably supported within. the upper bearing portionA.

To .hold the upper memberA of. the.

socket A in position and also to take up the wearI provide the following securing means. G are brackets secured tothe main frame. of the separator to each side of the socket support A". G are spiral springs extendin into the recesses A formed in the member A and bearing at their upper" end against the brackets G. By this means.

the socket member A is securely held in place so as to take up the wear between the sleeve-B and that should'the centrifuge be unevenly balanced the uneven motion will be taken up by the swing of the spherical" portion 13, in the socket formed by the members A and A l, the upper end being yield-- ably, anolresiliently supportedthereby insuring the smooth running of the machine and minimizing the wear upon thegears.

VVhat .I claim as my invention is, y

In a :cream separator, the combination with the mainframe and a socket support forming part, of the mainframe, ofa horizontally divided, member fitting within, the

socket support, an upper bearing portion,

also forming part of the bearing frame, a sleeve provided with the spherical boss, de-

signed. to fit the aforesaid horizontally divided member, resilient means for supporting the upper end of the sleeve in the 11 per:

bearing portion, a worm spindle held wlthin the sleeve in suitable bearings, a worm gear -mounted in the main frame and meshing H with the said spind1e, brackets secured tothe main. frame, and v compression springs held between the bracketsand the upper portion t of the horizontally divided member.
